First Superbowl Ever to be Played Under LED Lighting: A new Era in Lighting
Steve Taranovich 1/28/2015 35 comments
Unlike the disastrous Superbowl XLVII in 2013, when the Metal Halide stadium lights went out at an inopportune moment, Ephesus LED Sports Lighting, a US-based company that manufactures high-output LED lighting solutions for challenging applications in the industrial and sporting markets, has supplied the Stadium with high performance LED stadium lights.
The Power of the Printed Word

The MIT Age Lab recently worked with Monotype Imaging in an investigation of effects of typeface on the demand of human-machine interactions during a simulated in-vehicle point-of-interest (POI) menu selection task. Their study showed that people could perform a menu selection task faster and with more accuracy depending upon the text type used as well as white text on a black background vs. the standard block text on a white background. Differences were clearly noted.
Voice, Wireless or Infrared Control?

One of the key themes throughout my tour of CES 2015 exhibits was the wireless of infrared control of the Smart Home. Using your Smart Phone or Tablet, exhibitors showed how you could easily control many functions in your home.
Latchup and its prevention in CMOS
Keith Sabine 1/14/2015 5 comments
Early CMOS processes suffered a reliability concern that became known as latchup. It resulted in circuits either malfunctioning or consuming excessive power, and could be either inherent in the design or triggered by voltage spikes on IO pads that could forward bias PN junctions they were connected to.
An AC Current Generator, Part 4

In parts 1 through 3 I described the construction of the transformer we needed to generate the 10Amps AC. We still had to drive the transformer.
Analog circuit bliss can be yours, with a modest investment
Analog Angle 1/12/2015 11 comments
You can experience the joys and depths of analog circuit design by reading some recent, and not-so-recent, books; they explore topologies, error sources, components, and will likely spark some creative thinking about solutions to real-world circuitry issues.
Recently, AEye, was demonstrating their LiDAR system at CES in Las Vegas. A man using his new $1,198 Sony camera found that his photographs were damaged after he took pictures of AEye’s LiDAR LASER scanning system
The e-car basic concept is represented by the role of the electronics technology in making the car more comfortable, safe and effectively interacting with the driver. The first characteristic, comfort, is nowadays being dramatically enhanced by the new solution known as Road Noise Control (acronym: RNC) that has been introduced by BOSE during the CES 2019 in Las Vegas
Early microcontrollers had fixed I/O. It may have been possible to connect one of several internal peripherals to the I/O pins, but those pins were restricted and there was never an option of conditioning those outputs
In the not too distant past, if you were seen holding a conversation with a household appliance, you might have run the risk of being committed.
The voltage regulator is a very important part of the power management and the placement of voltage regulator plays an important role in improving the performance.
